IMPROVEMENT IN SELF-CLOSING DOORS FOR STOVES.

p cification forming part of Letters Patent No. 165,297, dated July 6,1875; application riled April 16, 1875.

in Stoves and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawing, and to the letters of reference markedthereon, which form a part of this specification.

Figure 1 is a'vertical section from front to rear. Fig. 2 is a frontelevation with a portion of the stovewall broken away. Fig. 3 is adetail in perspective.

It has been usual in stoves having the anticlinker or clinkerlessgrates, so called, to provide for the apertures or opening in the wallopposite the space between the ends of the fire-pot and the surface ofthe horizontal grate hinged or sliding covers or doors. While these canbe readily opened or closed at will, it happens occasionally that thesaid openings remain at times uncovered, through the neglect orforgetfulness of the persons having charge of the stove hence, the dustfrom the grate and ash-pit readily escapes into the room; hence, also,the draft of the stove is in some degree left open, and various otherannoyances and troubles arise.

The object of this invention is to provide a self-closing door for suchopening, all as will be now more fully set forth.

In the drawings, A-denotes the base or body of the stove, the lowersection only of which is now shown; B, the grate; O, the ashpit; D, theledge on which the lower end of the fire-pot rests. In the wall of thestove, at such convenient point or points in relation to the annularspace between the lower ends of the fire-pot and the horizontal grate astaste or design may dictate, are the opening or openings E, one or more,of any suitable shape, style or construction, their use and purposebeing merelyto-atford access through the wall or body of the stoveto thesaid space between the fire-pot and grate. To afford a suitable coverfor said openings I have provided a selfclosing door, F. In the presentinstance I have shown the frame of the opening E constructed with wallsthat slope upwardly and outwardly, so that the said door F, being hingedto the upper and inner edge of said or cover can be adjusted orappliedin various ways to accomplish this same end-for instance, the lower edgecan be weighted, or the said door or cover may, in a construction ofbase somewhat the reverse of the present, be hung or applied to theoutside. In these and various other equivalent ways I may. accomplishthe end now arrived at.

As thus made and constructed, when it is desired to gain access to thefire or coals in the space between the tire-pot and grate, it is onlynecessary to thrust the poker or slicer through the opening E in thebody of the stove. This movement throws the cover or door F away fromthe said opening only sufficiently far to admit the easy play of theslicer or poker in the operation upon the tire or coals, and when thesaid poker or slicer is withdrawn the cover immediately falls downautomatica ly into its proper position, and closes said opening.

In the method of construction now used for illustrating theabovedescribed invention, the lower edge of the door operates to scrapeoff all the dust or ashes from the poker or slicer as it is beingremoved from the opening, after it has been used to stir or agitate theburning coals in the fire-pot and on the grate.

Having thus described my invention, w h Iconsider new, and desire tosecure by Let ters Patent, is-

In combination with a stove body or base, having an aperture in its wallopposite the annular space between the grate and fire-pot, aself-closing door applied to said opening, substantially in the mannerand for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
